GT500 IC/HE Pump Comparison

[Robert M]

Whipple is doing this on the 2020 gt500 , claiming 40% more waterflow, very interesting...

Whipple Auxiliary Intercooler Pump (2020 Shelby GT500)

Is that Whipple pump kit an add to the existing system and its oem pump? or is it a replacement with a 40% greater water flow and a relocate? <<The link did not specify......Maybe that pump kit could be useful on the 2007-2014's? The pump looks 2013/14ish....

I would guess/hope that the 2020 does not have the tiny .55" passages at the intercooler in and out, like the 2007-2014 do inside that front lower intake adapter? <<The two o-ringed nipples bottle neck all of the coolant flow from the original 3/4" hoses down to just over 1/2" (.55).....

Robert, this is added in líne to the oem pump, ID venture to Say that the 2020 lines are not that small, it has a bigger and better brick and heat extractor hood to make up for a better overall system.

I agree, I am sure the 2020 I/C cooling system has had the shortfalls addressed that were issues for the 2007-2014's. A .55" passage in and out of the I/C on the 2007-2014 is quite small for significant coolant flow upgrades.

Actually, I think these same cross overs are carried over to the 2020 based on photos I've seen.

If that is the case, are .55" inlet/outlet nipples not as big a deal being that small size as has been thought? I mean the Ford SVT Engineers have wayyyy more R&D experience than most anyone I can think of as it relates to the Shelby GT500.......Are those small cross overs just fine for the S/C cooling system?........I mean now we are at an oem 760hp with some 2020's going well beyond that, and I would guess that some of them have not increased the inlet/outlet flow at the oem I/C.........If this has not been addressed by the SVE's during their trek to 760hp, then I would think it is not an issue that needed to be addressed? They certainly upgraded and/or changed everything else between 2014 and 2020......

Whipple pump mounted in line... wonder what pump is the new 2020 running...

That is Cool!!! The oem pump on the right looks like the 2013/14 CWA50 pump, or maybe even the CWA100?

I see a "bump" in the bracket holding the oem pump in place, there is a bump in the rubber mounting ring of the CWA100 that is not present on the oem 2013/14 CWA50......

Below is the CWA100 and note the "bump" in the rubber mounting ring......

^^^That "bump" will have a metal bracket with a corresponding bump/bend in it......

[Federico Garza]

By comparing online pictures, seems to be the cwa100 pump...

 

[Robert M]

Id definatley looks a lot like the 13/14 pump...

It does, and they are similar, but I also have a 2013/14 (CWA50) pump and all of the oem 2013/14 attaching hardware installed on my 2008 timing cover, and I don't think it has the "bump" in the rubber mounting ring like the CWA100......That bump is visible on the 2020 pump bracket mounting shown in that picture.

I think your right, comparing with online pics, seems the 2020 is using the cwa100 pump

I am not positive that is the case, but it seems to point the CWA100 direction.......I wish I could see the plug on the back end of the 2020 pump, the CWA100 points away from the pump which is different from the 2013/14 CWA50.....

Mine had that "bump". Here's a pic of the 13-14 pump with that raised section of rubber as well.

I'm sure this is a dumb question, but here goes...

Since a bypass is needed when running the 13/14 pump is it necessary to have two lines connected to the reservoir? I recently installed the VMP pump on my 04 and when I got home today there was a good amount of pressure in the tank. I have a True Forged tank so there's no breather. I was wondering if it would be ok to take the hose that's connected to the inlet of the tank and T it directly to the outlet hose as a bypass. The outlet hose will be covered by coolant constantly and I'd think the air would still be able to move up like how the radiator reservoir is connected.. Then I could convert the inlet side of the tank into a pressure relief.

 

[Catmonkey]

I don't think the tank should pressurize much if at all. Mine has never had excess pressure although I can't say I've ever opened the degas tank after parking it hot. If you have a way to see what your IAT2s look like, do so. I think heat is the only way to get pressure out of the intercooler system. I don't know about capping off the outlet on the degas. I don't know anyone that has ever done that.

Ok, then my memory was not correct, it has been a couple of years since I installed that 2013/14 pump on my 2008 and I did not remember a bump in the rubber......Maybe the 2020 does use the 2013/14 pump. I am glad you had the 2013/14 pump out for a visual comparison...

Even with the stock pump there would be some pressure if I checked it right when I got home.

I installed a VMP intercooler and saw about a 15 degree decrease in temps. I installed the pump and temps went back to what they were before the intercooler. When I was priming the new pump I saw some foam so I'm guessing its aerating the coolant in the tank right now.

The outlet from the tank would still be connected. The inlet to the tank would be open.

 

[Catmonkey]

It depends on how you mounted the pump. You can trap air in the impeller cavity if the pump motor is higher than the lines feeding it. It's easy enough to burp by slightly removing the inlet or outlet hose and letting any air escape. Same goes for the heat exchanger.

Will I be ok with the 13'-14' ic pump orientated like this?

Or... Based on prior comments, should I attempt to lay it down with the inlet laying on it's a side (parallel to the ground, on the same plane with the pump's electric motor)?

Thanks in advance.

Scratch that, after spending time skimming the thread, I changed the mounting orientation to this.

Feel free to remove my posts if needed to "clean up" the thread.

I don't think pointing the inlet straight down would be a good thing. You have gravity working against you. I've never seen any recommended orientations on the Pierburg pump, so it's anyone's guess.
